无法在android中实现描述符

我正在创build一个应用程序来查找两个图像之间的匹配。 我无法正确find匹配结果。

匹配方法给了我相同数量的描述符作为input关键点,我也无法得出这个结果。 我正在使用OpenCV作为工作区中的库。

这是我的代码。

Bitmap mBitmap1 = mimage1.copy(Bitmap.Config.ARGB_8888, false); Bitmap mBitmap2 = mimage2.copy(Bitmap.Config.ARGB_8888, false); Mat s_image1 = Utils.bitmapToMat(mBitmap1); Mat s_image2 = Utils.bitmapToMat(mBitmap2); Mat rgb1 = new Mat(); Mat rgb2 = new Mat(); Mat rgb3 = new Mat(); Mat temp = new Mat(); Mat o_image1 = new Mat(); Mat o_image2 = new Mat(); Mat o_image3 = new Mat(); List<KeyPoint> points1 = new ArrayList<KeyPoint>(); List<KeyPoint> points2 = new ArrayList<KeyPoint>(); List<DMatch> matches = new ArrayList<DMatch>(); FeatureDetector surf = FeatureDetector.create(FeatureDetector.SURF); surf.detect(s_image1, points1); surf.detect(s_image2, points2); Scalar color1 = new Scalar(0,255,0); Scalar color2 = new Scalar(255,0,0); Imgproc.cvtColor(s_image1, rgb1, Imgproc.COLOR_RGBA2RGB); Imgproc.cvtColor(s_image2, rgb2, Imgproc.COLOR_RGBA2RGB); Mat descriptors1 = new Mat(), descriptors2 = new Mat(); Features2d.drawKeypoints(rgb1, points1, rgb1, color2); Features2d.drawKeypoints(rgb2, points2, rgb2, color2); DescriptorExtractor extracter = DescriptorExtractor.create(DescriptorExtractor.SURF); extracter.compute(rgb1, points1, descriptors1); extracter.compute(rgb2, points2, descriptors2); int k = 5; DescriptorMatcher matcher = DescriptorMatcher.create(DescriptorMatcher.BRUTEFORCE); matcher.match(descriptors2, descriptors1, matches); Features2d.drawMatches(rgb1, points1, rgb2, points2, matches, rgb3, color1, color2); Imgproc.cvtColor(rgb1, o_image1, Imgproc.COLOR_RGB2RGBA); Imgproc.cvtColor(rgb2, o_image2, Imgproc.COLOR_RGB2RGBA); Utils.matToBitmap(o_image1, mBitmap1); mimageview1.setImageBitmap(mBitmap1); Utils.matToBitmap(o_image2, mBitmap2); mimageview2.setImageBitmap(mBitmap2); Utils.matToBitmap(o_image3, mBitmap3); mimageview3.setImageBitmap(mBitmap3); s_image1.release(); s_image2.release(); o_image1.release(); o_image2.release();
